I want to buy a couple of specific WD drives as they are on a tested hardware compatibility list for my NAS box.
The model specified in the list is WD20EARS-00S8B1.
What does the last bit after the - specify and is this important? All I find in online stores when I search is the WD20EARS and nobody specifies the end bit.
Does this have anything to do with the firmware running on the drive because this should be one of the newer 4K sector drives I think?
Thanks in advance…
